## Usage
|
37 |
+
|
38 |
+
In order to evaluate this model on an entire dataset, the evaluation codes available in the [whisper-finetune](https://github.com/vasistalodagala/whisper-finetune) repository can be used.
|
39 |
+
|
40 |
+
The same repository also provides the scripts for faster inference using whisper-jax.

+
In order to infer a single audio file using this model, the following code snippet can be used:
|
43 |
+
|
44 |
+
```python
|
45 |
+
>>> import torch
|
46 |
+
>>> from transformers import pipeline
|
47 |
+
|
48 |
+
>>> # path to the audio file to be transcribed
|
49 |
+
>>> audio = "/path/to/audio.format"
|
50 |
+
>>> device = "cuda:0" if torch.cuda.is_available() else "cpu"
|
51 |
+
|
52 |
+
>>> transcribe = pipeline(task="automatic-speech-recognition", model="vasista22/whisper-kannada-tiny", chunk_length_s=30, device=device)
|
53 |
+
>>> transcribe.model.config.forced_decoder_ids = transcribe.tokenizer.get_decoder_prompt_ids(language="kn", task="transcribe")
|
54 |
+
|

+
>>> print('Transcription: ', transcribe(audio)["text"])
